You Can Still Buy a Twin-Turbo Cadillac Blackwing V8 Engine From GM… For Now
As it turns out, the automaker built a few more 4.2-liter Blackwing engines than you might have originally thought.

Cadillac's 4.2-liter, twin-turbocharged Blackwing V8 was too pure for this world. Technically known as the LTA, it produced a maximum of 550 horsepower and 627 pound feet of torque with minimal turbo lag thanks to tiny, valley-mounted turbochargers. It only went in one car, the CT6-V, and only for two model years. When the CT6 ended production, the Blackwing V8 went with it; however, that's not quite the end of the story.

The engine, which was handbuilt at General Motors' Corvette production facility in Bowling Green, Kentucky, is still for sale on Cadillac's parts website. After discovering this, we reached out to GM to see what the deal was, and yes, as it turns out, you can still buy the Blackwing V8. According to a company spokesman, the automaker built a "handful of engines" for service use before production officially ended a few years ago. Assuming you can pay the $21,666.67 MSRP plus a $3,500 core charge, one of the unobtanium motors can be yours.

yeah....replacement parts for this will be non-existent down the road. It would be an expensive boat anchor if something major were to fail with no access to replacement parts.
If you have REALLY deep pockets, buy 3, and install one into a 1965 Cadillac Eldorado convertible. :)
